IPC: H04N19/426
Filed: 1998-11-30
Abstract: PROBLEM TO BE SOLVED: To provide image coding decoding method adopting the variable length coding system where coding is cancelled without causing image quality deterioration. SOLUTION: In the process of Huffman coding, an in-block Huffman code quantity (block code quantity) is counted and when the block code quantity exceeds a preset code quantity, a cancellation instruction is asserted to forcibly cancel Huffman coding processing and an end of block code EOBt is set to an end of block code data. In the process of Huffman decoding, cancellation f coding is detected by finding out the EOBt in a data stream. Since a high frequency component is lost in a pixel block where coding s cancelled, prescribed compensation processing is applied to recover an unsharpened edge.

Title: Simple flush toilet bowl
Inventor: KOSHIJIMA JIRO
IPC: E03D11/10
Filed: 1992-12-22
Abstract: PURPOSE:To obtain a simple flush toilet bowl which can be assembled easily into a compact structure while requiring less electricity. CONSTITUTION:A flap valve 9 which opens and shuts a discharge port 7 on the bottom of a toilet bowl is energized with a spring body 14 so that it can be pressed constantly against the discharge port 7. A kick spring 31 which gives the flap valve 9 a spring force acting contrary to the spring force of the spring body 14 when the flap valve 9 opens from its complete closure to a degree exceeding a specified angle is provided. While the flap valve 9 is in process of opening, the direction to which the spring force of the kick spring 31 is applied is reversed, and thereby the spring force of the spring body 14 is offset by the spring force of the kick spring 31. Even though the flap valve 9 is in the position of its maximum opening (by maximum spring force of the spring body 14), the flap valve 9 can easily be driven even with a small force.
